A -score takes a raw score and standardizes it into units of ________.
Assume the following 5 scores represent a sample: 2, 3, 5, 5, 6. Transform these scores into -scores.
True or false:a. All normal distributions are symmetricalb. All normal distributions have a mean of 1.0c. All normal distributions have a standard deviation of 1.0d. The total area under the curve of all normal distributions is equal to 1
Interpret the location, direction, and distance (near or far) of the following -scores:a. -2.00b. 1.25c. 3.50d. -0.34
Transform the following -scores into a distribution with a mean of 10 and standard deviation of 2: -1.75, 2.20, 1.65, -0.95
Calculate -scores for the following raw scores taken from a population with a mean of 100 and standard deviation of 16: 112, 109, 56, 88, 135, 99
What does a -score of 0.00 represent?
For a distribution with a standard deviation of 20, find -scores that correspond to:a. One-half of a standard deviation below the meanb. 5 points above the meanc. Three standard deviations above the meand. 22 points below the mean
